Abstract
The utility model discloses an extension tube of a vacuum cleaner. The extension tube comprises an outer tube, an inner tube sleeved into the outer tube in a sliding manner and a length adjustment component mounted at the rear end of the outer tube and used for selectively fixing the inner tube on the outer tube so as to adjust the length of the extension tube, wherein a sealing component is embedded into the front end of the inner tube; the end part of the sealing component extends out of the inner tube; a plurality of clamping groove rows are formed on the inner tube; a plurality of clamping grooves are formed in each clamping groove row at intervals in the length direction; and the front end of the inner tube is sleeved by a round tube-shaped sealing reinforcing member. The extension tube of the vacuum cleaner, provided by the utility model, has the advantage that the inner tube and the outer tube slightly sway when in use, so that the sealing performance is good.
Description
Technical field
The utility model relates to vacuum cleaner, refers more particularly to a kind of vacuum cleaner telescoping tube.
Background technology
Usually comprise in the vacuum cleaner; Can produce suction and reach main body of dust collector through inhaled air categorised collection material; And the suction through said main body of dust collector setting sucks extraneous air and the brush assembly that uses during the foreign matters such as dust that are inhaled into, and parts such as the telescoping tube that uses when being drawn into the foreign matter that sucks through the brush assembly and air in the air main body of dust collector again, handle component, bending type flexible pipe are formed.
Original telescoping tube locates to be embedded seal member at the front end (with the link of outer tube) of interior pipe; End diameter and outer tube diameter that interior pipe and seal member are stretched out in the end of seal member are suitable, stretch out formation sealing between interior end of managing and outer tube by seal member after the inner and outer pipe suit is accomplished.Owing to have the gap about 1mm between the inner and outer pipe; Inner and outer pipe produces and rocks during use, because inner and outer pipes length is longer, the value of rocking of pipe end can reach about 15mm; Influence is used; And be prone to make seal member stretch out in the end of pipe produce deformation, the sealing effectiveness variation influences the performance of vacuum cleaner.
The utility model content
The utility model technical problem to be solved is: inner and outer pipes rocked vacuum cleaner telescoping tube little, good seal performance when a kind of the use was provided.
For solving the problems of the technologies described above; The technical scheme that the utility model adopted is: the vacuum cleaner telescoping tube comprises outer tube, the interior pipe in the said outer tube that is slidingly located in; The front end place of interior pipe is embedded with seal member; Interior pipe is stretched out in the end of seal member, and interior pipe is provided with some draw-in groove row, and every row draw-in groove lists along length direction and is arranged at intervals with a plurality of draw-in grooves; The rear end that is installed in said outer tube be used on outer tube optionally fixing said in the length adjustment parts of pipe adjustment telescoping tube length, the front end sleeve of managing in said is provided with the sealing and reinforcing spare of pipe shape.
Said draw-in groove number of columns is two row, and isolates each other on the outer circumference surface of in said, managing, and said sealing and reinforcing spare is provided with two locating convex blocks that match with draw-in groove.
The periphery bottom of pipe is provided with along length direction and prevents the rail groove that rotates in said, and said sealing and reinforcing spare is provided with the anti-rotation projection that matches with rail groove.
Offer telescopic chute on the said sealing and reinforcing spare, telescopic chute is positioned at and axially connects whole sealing and reinforcing spare on the perpendicular bisector of two locating convex blocks.
Said sealing and reinforcing spare two ends respectively are provided with one and are convenient to sealing and reinforcing spare suit installation gap on inner pipe.
The beneficial effect of the utility model is: owing to be arranged with sealing and reinforcing spare on the interior pipe, inner and outer pipe is played the support fixation effect, reduced rocking relatively of inner and outer pipe, make that this vacuum cleaner telescoping tube is easy to use; And avoided seal member distortion in use simultaneously, and sealing fixture itself also plays certain sealing function, strengthened vacuum cleaner telescoping tube sealing on the whole greatly, improved the serviceability of vacuum cleaner.
Because sealing and reinforcing spare is provided with two locating convex blocks that match with draw-in groove, make sealing and reinforcing spare that the difficult slip in back on inner pipe is installed.
Because sealing and reinforcing spare is provided with the anti-rotation projection that matches with rail groove, make that sealing and reinforcing spare is difficult for rotating with respect to interior pipe.
Owing to offer telescopic chute on the sealing and reinforcing spare, telescopic chute is positioned on the perpendicular bisector of two locating convex blocks and axially connects whole sealing and reinforcing spare, make sealing and reinforcing spare suit be set in pipe last time more easy.

The specific embodiment
Below in conjunction with accompanying drawing, describe the specific embodiments of the utility model in detail.
Be depicted as a kind of embodiment of vacuum cleaner telescoping tube like Fig. 1-6; Comprise outer tube 1, the interior pipe 2 in the said outer tube 1 that is slidingly located in, the front end place embedding height of interior pipe 2 has seal member 3; Pipe 2 in stretch out the end of seal member 3; In pipe 2 be provided with two row draw-in grooves row, and isolation each other on the outer circumference surface of pipe 2 said in, every row draw-in groove lists along length direction and is arranged at intervals with a plurality of draw-in grooves 201; The rear end that is installed in said outer tube 1 be used on outer tube 1 optionally fixing said in pipe 2 adjust the length adjustment parts 4 of telescoping tube length; The front end sleeve of pipe 2 is provided with the sealing and reinforcing spare 5 of pipe shape in said, and said sealing and reinforcing spare 5 is provided with two locating convex blocks 501 that match with draw-in groove 201.In pipe 2 periphery top be provided with along length direction and prevent the rail groove 202 that rotates, sealing and reinforcing spare 5 is provided with the anti-rotation projection 502 that matches with rail groove 202.Offer telescopic chute 503 on the said sealing and reinforcing spare 5, telescopic chute 503 is positioned at and axially connects whole sealing and reinforcing spare 5 on the perpendicular bisector of two locating convex blocks 501.Sealing and reinforcing spare 5 two ends respectively be provided with one be convenient to sealing and reinforcing spare 5 be sleeved in the installation gap 504 of pipe on 2.
